I'm with Spam on this one. I think the Hi-Tec desert boot is called the 'Amazon' which is basically the Hi-Tec Magnum standard in suede and cordura. They are very comfortable and lightweight and hard wearing.
If they are the old style issue ones avoid like the plague, they are like the old DMS boot but made out of suede and i used them for a short while in the Middle East where they proved to be as uncomfortable as a pair of Barbed Wire underpants!
Very hard and unforgiving, blisters and sweat everywehere! I managed to get hold of some Yank ones and never looked back............until my next visit when i was issued the Hi-Tec's, Top Job!
There is a new type issued now but i've not worn them yet or had any reports about them so i don't know, but the Hi-Tec's are bob on!
